What is "_newtab" value for target attribute in HTML "a" tag? I can't find information about the compatibility for browsers.
Does it will work in all modern browsers?
How it will work if in browser option users set to open links in new window and not in new tab?
Does this value is described anywhere in HTML standards?
Are you sure, whether it is _new or _newtab?
There is no value called _newtab for target attribute.
May this SO answer gives us a better information,
Using target="_new" is technically invalid according to the
specifications, but as far as I know every browser will behave the
same way:
it will search for a tab or window with the context name "_new" *
if a "_new" tab/window is found, then the URL is loaded into it * if
it's not found, a new tab/window is created with the context name
"_new", and the URL loaded into it
Note target="_new" will behave exactly the same as target="new",
and the latter is valid HTML while the former is invalid HTML.
These are possible values for target attribute: _blank, _self, _parent, or _top
I think what you're trying to refer is target-new, a CSS3 property.
The target-new property specifies whether new destination links should
open in a new window or in a new tab of an existing window.
target-new:window; //Opens a link in new window
target-new:tab; //Open a link in new tab
Note: The target-new property is not supported in any of the major browsers.

I'm having hard time to find information related to target="_help" on the Internet. So, when I have an HTMLAnchorElement like this:
I can see that this thing is actually behaving like target="_blank", but anything else?
Could not find anything on MDN. Also no mention on the HTML5 Spec and detailed W3C Browsing Context page.
According to the MDN:
This attribute specifies where to display the linked resource. In
HTML4, this is the name of, or a keyword for, a frame. In HTML5, it is
a name of, or keyword for, a browsing context (for example, tab,
window, or inline frame).
That means that click on a
instructs iframe named _help to set src value to the value of href. The example below loads youtube video:
Help
<iframe name="_help"></iframe>
JSBin.
On a side note, this feature looks pretty obscure, I did not know about it before your question.
As mdn says:
target
This attribute specifies where to display the linked resource. In HTML4, this is the name of, or a keyword for, a frame. In HTML5, it is a name of, or keyword for, a browsing context (for example, tab, window, or inline frame). The following keywords have special meanings:
_self:
Load the response into the same HTML4 frame (or HTML5 browsing context) as the current one. This value is the default if the attribute is not specified.
_blank:
Load the response into a new unnamed HTML4 window or HTML5 browsing context.
_parent:
Load the response into the HTML4 frameset parent of the current frame or HTML5 parent browsing context of the current one. If there is no parent, this option behaves the same way as _self.
_top:
In HTML4: Load the response into the full, original window, canceling all other frames. In HTML5: Load the response into the top-level browsing context (that is, the browsing context that is an ancestor of the current one, and has no parent). If there is no parent, this option behaves the same way as _self.
So, if you use any other key except these 4 keys (_self, _parent, _top, _blank), it opens a blank window, and gives a name with the key you wrote on the target attibute to that window.

I see an onprogress when I inspect a Form element, on Chrome and Firefox (both latest stable versions). Can I use it to monitor the progress of the form submission?
I want to submit/upload a file (that will be big most of the time) to a server that is not under my control, I can't just do a POST to it with XMLHttpRequest because it won't send any of the CORS required headers. So I'm going for the form/iframe way, creating a form element with all the fields, add a file input, append to the file input the file instance I got from another dialog, create an iframe and set the target of the form to the name of the iframe.
Is this onprogress attribute something I can use? I can't find any docs regarding the onprogress attribute of a form. Is that just an inherited attribute or does it actually work?
I was looking into a solution for opening a page in new tab and then i landed on the CSS-3 property target-new
It states that: "If a user wanted to have new windows open in new tabs instead, she could use the following user style sheet to do so:
*{ target-new: tab ! important }"
I have couple of questions on it:
How it functions internally?
Why we don't have a property like target="_tab" in html5 specification but had this property as opening a link in new tab doesn't have any direct relation with Presentation?

No browser has implemented this yet.

target=_blank is still allowed because of backwards compatibility. Introducing new reserved target values, like _tab, wouldn’t work the same across browsers.
IMHO, the decision should be left to the user, and web authors shouldn’t force target=_blank or target-new: tab|window.
There is a legitimate reason for using Target=_blank that everybody has completely overlooked, and that is when a website is written as a BOOK with chapters/pages and the Table of Contents must remain intact without using the BACK button to reload the previous page (Table of Contents). This way all a surfer needs to do is close the Target Page when finished reading and they will be back to the Table of Contents.
Lucky for us that HTML5 has reinstated the Target="_blank" code, but unfortunately the "Block Popups" must be unchecked for it to work.
What's the difference between <a target="_new"> and <a target="_blank"> and which should I use if I just want to open a link in a new tab/window?
Use "_blank"
According to the HTML5 Spec:
A valid browsing context name is any string with at least one character that does not start with a U+005F LOW LINE character. (Names starting with an underscore are reserved for special keywords.)
A valid browsing context name or keyword is any string that is either a valid browsing context name or that is an ASCII case-insensitive match for one of: _blank, _self, _parent, or _top." - Source
That means that there is no such keyword as _new in HTML5, and not in HTML4 (and consequently XHTML) either. That means, that there will be no consistent behavior whatsoever if you use this as a value for the target attribute.
Security recommendation
As Daniel and Michael have pointed out in the comments, when using target _blank pointing to an untrusted website, you should, in addition, set rel="noopener". This prevents the opening site to mess with the opener via JavaScript. See this post for more information.
Using target="_blank" will instruct the browser to create a new browser tab or window when the user clicks on the link.
Using target="_new" is technically invalid according to the specifications, but as far as I know every browser will behave the same way:
it will search for a tab or window with the context name "_new"
if a "_new" tab/window is found, then the URL is loaded into it
if it's not found, a new tab/window is created with the context name "_new", and the URL loaded into it
Note target="_new" will behave exactly the same as target="new", and the latter is valid HTML while the former is invalid HTML.
Adding some confusion to this, in HTML4 the target attribute was deprecated. In HTML5 this decision was reversed, and it is an official part of the spec once again. All browsers support target no matter what version of HTML you are using, but some validators will flag the use as deprecated if your doctype is HTML4.
TL;DR
USE _blank
The target attribute specifies where to open the linked document.
USAGE: target="xyz" [don't forget double quotes]
_blank Opens the linked document in a new window or tab
_self Opens the linked document in the same frame as it was clicked (this is default)
_parent Opens the linked document in the parent frame
_top Opens the linked document in the full body of the window
framename Opens the linked document in a named frame
SINCE "_new" is not any of these IT WILL COME UNDER "framename" so if a user re-clicks on that hyperlink it will not open a new tab instead update the existing tab. Whereas in _blank if user clicks twice then 2 new tabs open.
I know this is an old question and the correct answer, use _blank, has been mentioned several times, but using <a target="somesite.com" target="_blank">Link</a> is a security risk.
It is recommended (performance benefits) to use:
Link
This may have been asked before but:
"every link that specifies target="_new" looks for and finds that window by name, and opens in it.
If you use target="_blank," a brand new window will be created each time, on top of the current window."
from here: http://thedesignspace.net/MT2archives/000316.html
target="_blank" opens a new tab in most browsers.
it's my understanding that target = whatever will look for a frame/window with that name. If not found, it will open up a new window with that name. If whatever == "_new", it will appear just as if you used _blank except.....
Using one of the reserved target names will bypass the "looking" phase. So, target = "_blank" on a dozen links will open up a dozen blank windows, but target = whatever on a dozen links will only open up one window. target = "_new" on a dozen links may give inconstant behavior. I haven't tried it on several browsers, but should only open up one window.
At least this is how I interpret the rules.
Caution - remember to always include the "quotes" - at least on Chrome, target=_blank (no quotes) is NOT THE SAME as target="_blank" (with quotes).
The latter opens each link in a new tab/window. The former (missing quotes) opens the first link you click in one new tab/window, then overwrites that same tab/window with each subsequent link you click (that's named also with the missing quotes).
_blank as a target value will spawn a new window every time,
_new will only spawn one new window.
Also, every link clicked with a target value of _new will replace the page loaded in the previously spawned window.
You can click here When to use _blank or _new to try it out for yourself.
The target attribute of a link forces the browser to open the destination page in a new browser window. Using _blank as a target value will spawn a new window every time while using _new will only spawn one new window and every link clicked with a target value of _new will replace the page loaded in the previously spawned window
In order to open a link in a new tab/window you'll use <a target="_blank">.
value _blank = targeted browsing context: a new one: tab or window depending on your browsing settings
value _new = not valid; no such value in HTML5 for target attribute on a element
target attribute with all its values on a element: video demo
The use of _New is useful when working on pages that are Iframed. Since target="_blank" doesn't do the trick and opens the page on the same iframe... target new is the best solution for Iframe Pages. Just my five cents.
I've curious how this should be properly done.
I ran a page im working on through the w3 html validateor and I got one error message
Line 47, Column 54: Attribute "target" exists, but can not be used for this element.**
<ul><li>1000 Design PM</li>
You have used the attribute named above in your document, but the document type you are using does not support that attribute for this element. This error is often caused by incorrect use of the "Strict" document type with a document that uses frames (e.g. you must use the "Transitional" document type to get the "target" attribute), or by using vendor proprietary extensions such as "marginheight" (this is usually fixed by using CSS to achieve the desired effect instead).
any idea on how i can have a link open a new window but not use the target tag?
You can use JavaScript to open new windows, which avoids the issue of target being invalid in modern HTML.
However, this bypasses various systems people have in place to warn them about new windows (or prevent them from opening) so you are better off using the target attribute (and switching to a Doctype that allows it).
Better still is to leave it to the user to decide when they want a new window. Aside from the annoyance factor, they do introduce accessibility problems.
target="_blank"
Will not validate strict because the 'target' attribute has been deprecated.
Instead, try something similar to the aforementioned onclick workaround, but you don't need the "_blank" in there either. Simply:
1000 Design PM
Will work. The reason for the deprecation of "target" is because HTML is used to semantically mark up data whereas the target attribute was providing behaviour, which is what javascript is for.
If the user has javascript turned off then the URL will simply open in the same window.
The target attribute is not part of the Strict variants of HTML 4 and XHTML 1.0 as well as XHTML 1.1.
So you would need to use a workaround using JavaScript:
1000 Design PM
var aElems = document.getElementsByTagName("a");
for (var i=0, n=aElems.length; i<n; ++i) {
if (/(?:^|\s+)_blank(?:\s+|$)/.test(aElems[i].className)) {
aElems[i].onclick = function() {
return !window.open(this.href, "_blank");
}
}
}
Or (in the future) CSS 3 (see Hyperlink Presentation Module):
a._blank {
target: new;
}
Shouldn't it be...
target="_blank"
Regardless... You could open a new window using javascript, but that breaks the beauty of simple browsing. What if I'm browsing using Lynx or something?
According to W3C, it seems that "target" attribute is not deprecated any more in HTML 5:
The target attribute for the a and area elements is no longer
deprecated, as it is useful in Web applications, e.g. in conjunction
with iframe.
http://www.w3.org/TR/html5-diff/
Using:
target="_blank"
breaks strict XHTML validation methods. Here's a document detailing a workaround:
Instead of target="_blank" (who will never validate) you could use javascript like this:
<a onclick='window.open("./jobops/1000 Design PM.pdf", "_blank");return false;' href="./jobops/1000 Design PM.pdf">1000 Design PM</a>
Then the link will open in a new window, and your page will validate.
The users who doesn't have Javascript enabled (even though that is only about 2% of all users), will still be able to follow the link with this method. The guy's have a good point in the comments :)
Have a nice weekend everyone...
